X8DTN+ User’s Manual

C1E Support

Select Enabled to use the feature of Enhanced Halt State. C1E signiﬁ cantly reduces

the CPU's power consumption by reducing the CPU's clock cycle and voltage during

a "Halt State." The options are Disabled and Enabled.

Hardware Prefetcher (Available when supported by the CPU)

If set to Enabled, the hardware pre fetcher will pre fetch streams of data and instruc-

tions from the main memory to the L2 cache in the forward or backward manner to

improve CPU performance. The options are Disabled and Enabled.

Adjacent Cache Line Prefetch (Available when supported by the CPU)

The CPU fetches the cache line for 64 bytes if this option is set to Disabled. The

CPU fetches both cache lines for 128 bytes as comprised if Enabled.

Intel® Virtualization Technology (Available when supported by the CPU)

Select Enabled to use the feature of Virtualization Technology to allow one platform

to run multiple operating systems and applications in independent partitions, creat-

ing multiple "virtual" systems in one physical computer. The options are Enabled

and Disabled. Note: If there is any change to this setting, you will need to power

off and restart the system for the change to take effect. Please refer to Intel’s web

site for detailed information.

Execute-Disable Bit Capability (Available when supported by the OS and

the CPU)

Set to Enabled to enable the Execute Disable Bit which will allow the processor

to designate areas in the system memory where an application code can execute

and where it cannot, thus preventing a worm or a virus from ﬂ ooding illegal codes

to overwhelm the processor or damage the system during an attack. The default is

Enabled. (Refer to Intel and Microsoft Web Sites for more information.)

Simultaneous Multi-Threading (Available when supported by the CPU)

Set to Enabled to use the Simultaneous Multi-Threading Technology, which will

result in increased CPU performance. The options are Disabled and Enabled.

Active Processor Cores

Set to Enabled to use a processor's Second Core and beyond. (Please refer to

Intel's web site for more information.) The options are All, 1 and 2.

Intel® EIST Technology

EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically

adjust processor voltage and core frequency in an effort to reduce power consump-
